How cold of air can I run with my air cooled hood?

it gets very cold up here and I wanted to know if I could run 20deg air through my 6" mag air cooled hood? I didnt know if it would be bad for the bulb or not.

\thanks

do the street lights still work when it's zero degrees..they are hps lights..lil dif being enclosed like that but yes it will work.

if anything it will be good for the bulb

Dam, im dumb. thanks alot.

no need for that just have to look at what you are asking..good luck have a good night

Might as well make the heat from the bulb warm up your place; no?

I have zero experience with these lights, however, I have been looking at buying one and I have noticed they have a functional temp range listed in the specs. Really doesn't come into play with me, but thought I would share since I saw that today

i run an ac vent through mine in the summer...the glass is actually cold...never had a prob...be using outside this winter... free ac
